Gummi

Gummis (Japanese: グミGummi) are consumable items found in Pokémon Mystery Dungeon. Gummis come in a variety of colors, and have varying effects based on where they are applied. In all instances, eating a Gummi will increase a Pokémon's IQ, allowing it to learn more IQ Skills, with better-tasting Gummis increasing the value by a greater amount.

In Pokémon Mystery Dungeon Red and Blue, when a Gummi is eaten inside a Friend Area, one of the recipient's stats increases (or rarely, all stats). Inside a dungeon, eating a Gummi will fill one's Belly: 60 Belly if it matches Pokémon's type, 30 if it weakens it, 25 if it's neutral, 20 if it is resisted by, and 5 if it's ineffective on it. In case of Pokémon with two types, the numbers are added (eg. Grass Gummi would refill 80 of Hoppip's Belly, as it matches its Grass-type and is resisted by its Flying-type). Gummis are found in dungeons and as mission rewards. The Stormy Sea contains every Gummi.

In Pokémon Mystery Dungeon Time and Darkness, stat gains occur randomly when they are eaten in dungeons. Gummis also increase belly size by 5 if eaten when full. The player is able to buy Gummis for 800 Poké. Wonder Gummis are never available for purchase, and Gold Gummis are rarely seen in shops. Most Gummis will be found in dungeons that match the type that likes the certain Gummi the most.

There are many varieties of Gummi; each individual color is best received by a particular type. In Explorers of Time/Darkness, the Gummis are exclusive by game and the Gummis that cannot be found in the game are only found in a certain area of Zero Island North and in Monster Houses or Treasure Chests.
